Struct BlobCreatorProxy 

pub struct BlobCreatorProxy { /* private fields */ }

Implementations

impl BlobCreatorProxy

pub fn new(channel: Channel) -> Self

Create a new Proxy for fuchsia.fxfs/BlobCreator.

pub fn take_event_stream(&self) -> BlobCreatorEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn create( &self, hash: &[u8; 32], allow_existing: bool, ) -> QueryResponseFut<BlobCreatorCreateResult, FDomainResourceDialect>

Creates a blob with the merkle root hash. If allow_existing is true, the server will overwrite the existing blob if there is one. The server may fail this request with [CreateBlobError.ALREADY_EXISTS] if there is already an inflight BlobWriter for the same hash which has not been closed or completed. The client will truncate the blob with [BlobWriter.GetVmo] and get a handle to a vmo in return. The client will then write blob contents into the vmo and call [BlobWriter.BytesReady] on the ’writer` to signal to the server that some number of bytes has been written to the vmo.

pub fn needs_overwrite( &self, blob_hash: &[u8; 32], ) -> QueryResponseFut<BlobCreatorNeedsOverwriteResult, FDomainResourceDialect>

Given the hash of a blob, returns true if it should be overwritten using Create with allow_existing set to true. Must respond the same as BlobReader.GetVmo in terms of existence checks, responding ZX_ERR_NOT_FOUND under the same conditions.

impl BlobCreatorProxyInterface for BlobCreatorProxy

type CreateResponseFut = QueryResponseFut<Result<ClientEnd<BlobWriterMarker>, CreateBlobError>, FDomainResourceDialect>

type NeedsOverwriteResponseFut = QueryResponseFut<Result<bool, i32>, FDomainResourceDialect>

fn create( &self, hash: &[u8; 32], allow_existing: bool, ) -> Self::CreateResponseFut

fn needs_overwrite( &self, blob_hash: &[u8; 32], ) -> Self::NeedsOverwriteResponseFut

impl Clone for BlobCreatorProxy

fn clone(&self) -> BlobCreatorProxy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlobCreatorProxy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Proxy for BlobCreatorProxy

type Protocol = BlobCreatorMarker

The protocol which this Proxy controls.

fn from_channel(inner: Channel) -> Self

Create a proxy over the given channel.

fn into_channel(self) -> Result<Channel, Self>

Attempt to convert the proxy back into a channel.

fn as_channel(&self) -> &Channel

Get a reference to the proxy’s underlying channel.

fn domain(&self) -> Arc<Client>

Get the client supporting this proxy. We call this a “domain” here because:

fn on_closed(&self) -> OnFDomainSignals

Returns a future that completes when the server receives the PEER_CLOSED signal.
